SOLUTION CHARACTERISTICS
1. Software used : EPOS.P.V2
2. Definition of Terrestrial Reference Frame
Fiducial-free adjustment of all station coordinates.
These coordinates are then fixed in the determination of ERPs and ORBITS
3. Data used:
- undifferenced carrier phases
- 32 h arc solutions
5. Adjusted parameters:
- state vector of all satellites
- coordinate corrections
- daily ERPs
- tropospheric zenith path delay (4 h)
- y-bias, solar radiation scaling factor
- ambiguities
- STA and SV clock parameters of each observation epoch
